摘要

We investigated configurations of cladding pumped MC-EDFA with pump recycling to improve optical amplification efficiency. Spatial injection fibre reinjection with spatial splitting configuration offers additional 3.5 dB of optical gain and 3.5 dB of output power, compared to standard cladding pumping without pump recycling.
